We look at the division of 707325 by 72 
The aim is to understand the frequency of 72 in 707325.

Advancing to step 1:
When dividing 7 by 72, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 72

Going ahead to step 2:
72 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 72

Step 3:
If we divide 707 by 72, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 648 from 707 and we're left with 59.
Include the next digit (3) from the dividend after 59, then repeat: 593 / 72

On to step 4:
593 divided by 72 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 576 from 593, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 72

Moving on to step 5:
72 goes into 172 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 982.0
The remainder is 28 after subtracting 144 from 172.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 72

Let's proceed to step 6:
72 goes into 285 3 times with a remainder of 69.
The next digit of our result is 3. 
Result so far: 9823.0
If we subtract 216 from 285, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
The number 72 fits into 690 9 times, leaving a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 9823.9
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
420 divided by 72 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 9823.95
Deduct 360 from 420 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 72 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 9823.958
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
240 divided by 72 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 9823.9583
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 9823.95833
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 9823.95833 with a remaining 2.4e-05.
